[16] RFR(XS) 8248347: windows build broken by JDK-8243114

[Vladimir Kozlov]

Resending to groups mailing lists since hotspot-dev is behaving strangely today.

https://bugs.openjdk.java.net/browse/JDK-8248347

I used ULLONG_MAX instead of -1ULL [1].

I ran tier1. Tests still run on MacOS. Linux and Win are finished.
Builds passed on all our supported x64 OSs: Linux, Win, MacOS.
Tier1 runs MontgomeryMultiplyTest.java test - it passed on Win.

Thanks,
Vladimir
